Oleg, where did RIOT find those values for CPUID:
#define SAMD21_CPUID_WORD0 (*(volatile uint32_t *)0x0080A00C)
#define SAMD21_CPUID_WORD1 (*(volatile uint32_t *)0x0080A040)
#define SAMD21_CPUID_WORD2 (*(volatile uint32_t *)0x0080A044)
#define SAMD21_CPUID_WORD3 (*(volatile uint32_t *)0x0080A048)

Basically, if I fill the CPUID with my new EUI64 (in correct order) at
boot time (before reset at86rf2xx), it will update all iface values (I
tried it) or I should edit cpuid_get as I want.

Last question, I saw that RIOT automatically edits the universal/local
(U/L) flag (bit 7) in the OUI portion
Long HWaddr: 5a:5a:XX
inet addr fe80::585a:XX

If I've got a global EUI64, not local, how should I proceed to tell
RIOT to not create local address? Or did I misunderstand something?
